    Loftus Versfeld stadium

    Established in 1892, with a factory in Pretoria,the company supplied cement to build many

    of the countrys landmarks. Through chang-ing times and landscapes, the company

    has maintained

    its leadership positionwithin the building indus-

    try and although brandsand packaging havechanged, the formula

    to provide builders withthe best quality cementfor every occasion never

    This year, the company

    celebrates its 100th an-niversary on the Johannes-

    burg Stock Exchange (JSE).

    We look back at the milestonesreached along the way. PPC can

    truly celebrate the role it has playedin building our nation.

    12 decades of milestones1888 - Edouard Lippert gets permission from PaulKruger, President of the Transvaal Republic, and the

    Volksraad to set up a local cement factory on theoutskirts of Pretoria, which was to become PPC.

    1890 - President Paul Kruger formally opened thecement factory outside Pretoria named Hercules,

    which still exists today.1892 - The Eerste Cement Fabrieken Beperkt is regis-tered as the company to operate the factory.

    1902 - The Eerste Cement Fabrieken changes its nameto The First Portland Cement Company.

    1908 - TheFirst Portland

    Cement Compa-

    ny changes its nameto the Pretoria Portland

    Cement Company Limited and

    declares its rst dividend. The com-pany has not failed to pay a dividend since.

    1910 - Eighteen years after its inception, PPC is listedon the Johannesburg Stock Exchange.

    1916 - PPCs new Slurry factory in the North WestProvince produces its rst cement.

    1921 - PPC establishes the Cape Portland CementCompany and builds a factory at De Hoek.

    COVER STORY

    Then and nowConceived in 1888, during the early gold rush

    days on the Witwatersrand, the growth anddevelopment of both PPC and the JSE weremarked by many memorable periods of cop-

    ing with major internal and external inuences including two world recessions, two WorldWars and a great deal of national political

    turmoil leading to democracy in 1994.

    Today, 118 years after its inception, PPC Ce-

    ment has eight manufacturing plants andthree milling depots in South Africa, Botswana

    and Zimbabwe. Together, these facilities arecapable of producing almost eight-million tonsof cement products a year. Related products

    include aggregates from the companysGauteng and Botswana quarries.

    PPC Lime is southern Africas foremost supplierof metallurgical-grade lime, burnt dolomite,limestone and related products. The companys

    Lime Acres operation in the Northern Cape isone of the largest lime plants in the world.

    2006 - PPC becomes a constituent on the JSE SociallyResponsible Investment Index.

    2007- PPC is ofcially unbundled from Barloworldhaving become a subsidiary in 1977.

    2009 - PPC establishes its Broad Based Black EconomicEmpowerment transaction which directly benetsapproximately 3,5 million people in South Africa, the

    In the last 118 years the Pretoria Portland Cement

    Company has grown from strength to strength,

    not only through our cement, aggregates and lime

    production, or all the South African landmarks

    weve helped build from the ground up, but also

    by our commitment to building the history and

    lives of our employees, our shareholders, and of

    course, all South Africans.

    Weve never forgotten that its the people that

    make us strong, and thats why, in 1998 we

    adopted the Kambuku philosophy, a Tsongaword for Great Tusker, meaning tenacity and

    loyalty, attributes all our employees embrace as

    an integral part of who we are. PPC has also

    transformed with our country, and is proud to be

    rated a level 3 BBBEE contributor a truly South

    African Company.

    Its not every day that a company reaches

    100 years listed on the Johannesburg Stock

    Exchange and for this, we would like to thank

    all our stakeholders, over all these years, who

    have travelled this road with us. We ask that you

    PAVING

    When paving is installed while constructionis still taking place around it, contractors

    should use the following techniques toensure the paving looks good whenthe handover takes place.

    David provides the following tips and tricks to keeppaving in tip-top shape:

    General cleaningRegular hosing and sweeping will keep your pavinglooking clean. To remove general dirt and debris, you

    should hose down your paving and sweep it with ahard bristled outdoor broom regularly. If the paving

    is soiled, scrub the area with a general purpose, pHneutral/slightly alkaline, non-abrasive cleaner, using

    a hard bristled brush or broom together with someelbow grease.

    WeedsIt is a common misconception that weeds growthough the paving, says David. This does occur in

    rare cases; however, weeds almost always grow fromseeds and bird droppings that land in the jointing

    sand and are left undisturbed to germinate. Regularhosing and sweeping of the paved area wil l preventweeds from taking root. Alternatively, treat the pav-

    ing with a general-purpose organic weed killer twoor three times a year.

    CleaningPaving

    Before

    Hand-overThere is no such thing as maintenance-free paving. David Wertheim Aymes, CEO of the Bosun Group, says

    that a well-planned cleaning and maintenance programme is the only way to ensure that the overall appear-

    ance of your paving will be enhanced.

  • 8/7/2019 SOS: Apr 2010

    8/40 Skills on Site April 2010

    Stain removal and spot treatmentsFirstly, it is important to eliminate the source of thestaining. Most stains can be removed by scrubbingthe area with hot soapy water, but if they are par-

    ticularly stubborn stains, cleaning the area with anacid-based cleaner may be required.

    However David cautions that acid-based cleanersshould only be used on the stained area and not as ageneral cleaning solution. He also advises that acid-

    based cleaning be undertaken by a professional.

    Paving maintenancePaving should be inspected four times a year to checkfor any loose, damaged or stained paving and to

    ensure that the jointing material is intact. Shouldyou discover loose paving, it is important to rectifythe cause of the movement, says David. No matter

    what the cause, it needs to be investigated and xedbefore replacing or re-bedding the paving units.

    David says that individual blocks of the damagedor stained paving can easily be replaced. Jointing

    material in newly-laid paving may be lost from earlyon because the joints have not yet become stabilised

    naturally or chemically. It is therefore important to

    inspect areas of new paving regularly in their earlylife and top up joints if necessary, says David. If the

    jointing material is no longer intact, the pavers simplyneed to be topped with jointing sand by brushingor sweeping in dry jointing sand as required.

    Sealing of block pavingAny form of surface sealing used on the paving

    must be applied in strict accordance with the

    manufacturers instructions; however David warnsthat sealants may have an effect on the colour ofthe paving. In addition, he says that its slip/skid re-sistance may require on-going maintenance during

    the life of the paving. It is also important that thesurface of the units is dry, clean and eforescence-free before any sealer is applied, he says.

    EfflorescenceEforescence is a whitish lm that becomes visibleon the surface of the pavers.

    It consists mainly of insoluble calcium carbonate(CaCO2) and should be seen as a passing nuisance,says David. This white haze is a natural phenomenon

    that occurs in all concrete products as it is a naturalby-product of all hardened concrete.

    While eforescence will fade over time, it can alsobe reduced and in some instances removed by using

    diluted hydrochloric acid. Once again, this shouldrather be undertaken by a professional.

    Keeping paving well maintained through regularcleaning and checks for problem areas will preventthe likelihood of some sections, or even the entire

    paved area, from needing to be replaced.

    Whether paving a walkway or a road with concrete,

    clay bricks, or blocks, a number of basic principles

    should be kept, in order to ensure the paving stays

    in place and stays looking good for many years. With

    these easy-to-follow instructions, it is possible to

    manually pave roads, driveways or walkways.

    M

    ake a plan

    A good plan is essential to a successful

    paving project. Think about where youwant your path, driveway, or patio, and

    then use graph paper to make a drawing of the im-mediate area. Youll have to play around with yourdesign a bit, so be sure to use a pencil and keep your

    drawing neat. Your project will need to have adequatedrainage if you want it to be safe and long lasting.Youll also want to make sure that it slopes away from

    your house and other structures. To ensure adequatedrainage, you should have a good slope.

    Even simple paving projects can look good. Youcan do a lot more with pavers, though, so consider

    making patterns or unusual shapes.

    Order your materials. You have a lot of choicesin the pavers you use. Most are brick or con-crete and prices vary from supplier to supplier.At your local builders supply store, you can nd a

    style that is easy to lay and that ts your budget.

    You can safely calculate how many pavers you needby simply measuring the area and adding 5 percent.If your design has a lot of curves, buy an extra 10%

    over your required amount. You should order extrabecause youll almost certainly end up having to cutsome of the pavers to get the right t.

    Outline the project area. Use string to outline yourproject. Drive stakes to hold the outline in place and

    to make clean corners.

    Scope your slope. To avoid water pooling on yourpavers, they should be slightly above the surface of

    the surrounding ground at all points. When planningthe slope, begin at the highest point.

    Drive a stake at the high point, and mark the correctheight where the pavers will meet the joining structure.

    Tie a string around the stake at that height.

    Drive a stake (if there isnt already one) at the outer

    boundary of your project. This will be your lowest point.Attach a line level to your string and then tie the looseend of the string around the stake at the height at

    which the line level tells you the entire string is level.Now, from that line move down the stake at least 1/8

    per metre (eg , if it is 8 metres from the front door tothe outer edge of the road, move down the stake 1metre), and draw a new line. Move your string down

    to this line. String cross-lines down the length of theproject to ensure you mark the correct depth across

    the entire project.Measure the depth of your excavation frequently.Measure from the line, not from the surface of the

    ground.

    Excavate the installation area. Spaces which will beexposed only to foot trafc generally need 10 15cm

    of base material, while driveways need as much as30cm and roads still more. Figure out how deep yourbase will need to be (consult the manufacturer or

    your building supply store). The sum of the depth ofthe base, the sand, and the pavers will be how deepyou need to excavate your project area. Be sure to

    excavate 30cm past the edge of the project to giveyou space to install edging concrete.

    Measure the depth of your excavation from the stringyou used to track your slope, not from the surface ofthe ground. Once youve nished excavating, use a

    plate compactor to compact the base.

    Lay the base. The base material is usually coarse,crushed stone with sharp irregular edges. Add no

    more than 5cm at a time to the entire excavatedarea, and then compact it with a hand compactor(for very small projects) or a plate compactor (for

    larger ones). It is important that the base be well-com-pacted and thereafter, each layer in turn. Repeat thisprocess until you have a base of the correct depth.

    TipsIf you are working in sandy soil, you may mixPortland cement into the soil as a base. Do this

    only if youre installing a walkway or patio thatwill receive only foot trafc.

    Clay soil can move over time and you can add

    stability to your project by covering the bottom andsides of the excavation with a weatherproof fabric

    or plastic layer before you add your base.

    Spray your base gravel lightly with water to

    moisten it. This will make it easier to compactthe base correctly.

    the sand. Do not slide them along the ground or kickthem into place and disturb the sand. Slide each

    paver straight down the edge of the adjacent paver.Dont worry about gaps: you generally want to leavea gap between pavers. From time to time, check to

    make sure the pavers are level, and use a string tocheck each row for straightness.

    You might need to cut some pavers to t the edges.Dont try to curve your pavers to t the edging. In-stead, lay all the whole pavers you can in each row

    and then go back and cut pavers to the correct sizes

    to t the edge. Use a masonry saw or a guillotine-stylesplitter to make good, clean cuts.

    Do not step on your prepared sand. Stand on the

    pavers you have already installed and work yourway out. Dont get too close to the edge of the pav-ers youve installed, or you might disturb the sand in

    front of them.

    Use a plate compactor to tamp the pavers intothe sand. Once all the pavers are installed, run theplate compactor over them to ensure they are snug-

    gly pressed into the sand.

    PAVING

    Now is your last chance to properly adjust the heightof the nished project and to ensure you dont haveany dips or bumps. Slightly increase or decrease the

    thickness of the base as necessary, taking frequentmeasurements from your strings to the base. Laying

    the base outside the boundaries of the project willmake your project more stable.

    Temporarily edge the paving with bricks or wood

    planks and secure them with spikes. Concrete theedges as required. Concrete or brick edges will help

    hold the shape of your project over the years.

    Put down a layer of sand. The sand is the gluethat holds your pavers in place. Use coarse sandand screed it smooth to a uniform depth of about

    3 - 4 cm. If your project is big, lay down planks andthen pour the sand in between, screeding the sandin small sections. Remove the planks and then ll in

    the gaps with more sand.

    Lay the pavers. Begin laying pavers at a 90 corner,preferably one that joins another structure. Workoutwards from there, keeping your pavers in straight

    lines. Lay pavers by placing them straight down in

  • 8/7/2019 SOS: Apr 2010

    13/40Skills on Site April 2010 1

    Sweep sand into the joints. Fill the joints betweenpavers with coarse sand like you used earlier, or useslightly ner sand. Pour it onto the pavers and sweep

    it into the cracks until they are completely lled. Thissand locks the pavers in place. Make sure the sand

    is dry.

    But, it is the unfortunate customer who pays

    the price when things go wrong, especiallyfurther down the line when the contractorhas gone bankrupt and moved into swim-

    ming pool construction. The unlucky clientmust then look for a competent professional to re-lay

    the entire installation.

    Strict specificationsThere is much more to paving than meets the eyeand what may look acceptable or even logical isoften the opposite of good paving practice. It was

    with this in mind that the Concrete ManufacturersAssociation (CMA) laid down strict standard speci-cations on what a paved surface should be and

    how it should be built. Attention to detail and properpreparation of the substrate material are very impor-

    tant; so are choosing the right people and suitablepaving materials.

    How then do you ensure that your chosen sub-con-

    tractor can deliver? The preferred route is to use aCMA-approved contractor whose work is based on

    CMA paving standards. It is also guaranteed, bothby the contractor and the CMA. In the unlikely eventof a problem arising, CMA-approved contractors are

    obliged to make good at their own expense.

    The right sub-contractorCMA director, Hamish Laing, cautions further thatchoosing the right sub-contractor can still result in

    failure if the paving stones are not up to standard.

    Here again, the best course is to source concreteblock pavers (CBP) from a CMA manufacturer. An ap-

    proved contractor will do this automatically providingthe customer asks him to supply the pavers.

    Good workmanship using a poor quality product will

    result in unhappiness further down the line, and vice

    versa, poor quality workmanship with an approvedconcrete paver will produce the same result. Only acombination of high quality CBPs and workmanshipof a high standard will achieve the desired result a

    surface which provides decades of maintenance-free use.

    Attention to detailAs in any professional installation, attention to detail iscrucial to competent paving. For instance, a problem

    which occurs with regularity, especially in domesticinstallations, is untidy edge restraints. These should be

    kept below the paving surface so that they are not

    visible, as is so often the case.

    Another misplaced belief is that plastic sheetingplaced under pavers will prevent weed growth. Itdoesnt. Seeds are blown into the spaces between

    blocks from the top and grow whether there is plasticsheeting or not.

    Plastic sheeting problemsPlastic sheeting also breaks the bond between thebedding sand layer and the base soil . This can cause

    what is known as creep i.e. horizontal movement ofpaving sections, especially if the installation is situated

    on a slope. Sheeting can also act as a dam when itrains, which causes saturation of the bedding sandand pumping of the pavers, both of which lead to

    failure of the installation, advises Laing.

    CAPENTRY

    When hanging a door, it is important

    that you get it right so that the door tsproperly. Use the following steps to hangwooden doors.

    Measure the door openingUsing a tape measure, measure the height and width of

    the door opening. Write the measurements down.

    Purchase a doorThe door should be slightly smaller than the nishedopening to allow a space for closing the door. Thereis also room to buy a door that is a little bigger, as

    you will be trimming it.

    Mark the door for

    trimmingUse a pencil to applythe measurements.Generally, allow

    for a 2mm spacebetween the doorand the top and

    sides. The bottomof the door should

    be 6-12mm up fromthe oor (considerwhether the door is

    going to have to goover carpet or tiles). Ifyour measurements

    were 1992mm highand 768mm wide,

    for example, markthe door so thatits 1984mm tall

    (1992mm minus 2mmfor the top and 6mmfor the bottom) and

    764mm wide (768mmminus 2mm for each

    side).

    Trim the door

    Saw or plane up tothe pencil marks,then sand the edges

    until they are smooth.Keep in mind thatyoure better off trim-

    Cut hinge recesses (mortises)Use a chisel to make shallow recesses, called

    mortises, in the door, within the pencil marks. Stripaway the extra wood and trim the recess until the

    hinge is ush with the wood. Be careful - if you chiselout too much, it will be very hard to x.

    hinges and use a drill bit that is slightly narrowerthan your screws to drill pilot holes where they

    are marked by the pencil. To centre the pi lotholes perfectly, use a special bit called a vixbit, available at any hardware store or home

    centre. When using a vix bit, drill through thehinges screw holes with the hinge in its properlocation on the door. Keep the bit perpen-

    dicular to the door.

    Screw on the hingesThis is best done with a drill, but can also be donewith a screwdriver if necessary.

    Mark the hinge positions on

    the framePlace objects such as screwdrivers

    or shallow wedges at the bottom ofthe doorway. Have somebody holdthe door in the frame in exactly the

    position that you want it to hang.The hinge knuckles should be paral-

    lel with the frame. Draw around thehinges with a pencil. After carefullyputting the door aside, cut mortises

    in the door frame in the same waythat you did on the door itself. Holdthe door against the frame again

    to test the placement and makesure the hinges are ush. Mark pilot

    holes on the frame with a pencil andthen drill through these marks in thesame way you did for the door. Put

    the screws through the pilot holes tofasten the hinges on the frame.

    Easy tips When using the plane, avoidchipping off the corners of the door

    by working inwards from each edgetowards the centre.

    Only put one screw in each hinge to begin with soyou can test that the door closes easily in the frame. If

    you are happy, then screw in the remaining screws.

    Add a door stop if you are concerned about thedoor bumping into, and marking, the wall behind it.

    There are many different types of doorstops.

    Information from www.wikihow.com

    to help you, hold it up, place the door in the frameand see if it ts properly. If it doesnt, you will need to

    trim again until the t is perfect.

    FittingDetermine in which direction the door will open. Thedoor should open in to the room and hinge place-

    ment should be such that the light switch is acces-sible on the side opposite the hinges. If, as you enterthe room, the light switch is inside on the wall to yourright, then the hinges should be on the left, so that

    as you push the door open to enter the room, theswitch is immediately accessible on the knob side

    of the door.

    Place the door on its side with the hinge side upwards.

    Measure and mark 15cm from the top and bottomof the door. This mark represents the bottom of thehinge at the bottom of the door, and the top of the

    hinge at the top.

    Open a hinge and place it on the door in line withthe mark you have just made. Draw around it with apencil. Repeat this for the other hinge.

    Light side of a dark momentDespite the seriousness of the struggle Chris stills

    laughs when he remembers a youthful mistakethat cost him 9-months in prison following the

    1976 uprising.

    As a teenaged activist I was targeted by the po-

    lice and arrested. But, being young and thinkingI was clever and outsmarting the system, I gavethe wrong name at the time of my arrest.

    After spending many months behind bars at Fortand Modderbee prisons I was eventually released

    when my parents nally tracked me down. It turnsout that when they found out I had been jailedthey went to bail me out, but couldnt nd me.

    Had I given the right name they would have beenable to set me free much sooner, he recalls.

    SUCCESS

    T

    hat is how Chris Jiyane, business developmentand transformation director of LTA Grinaker

    Buildings life has turned out. He is living hisdream. He has achieved almost everythingthat he strived for as a young man and as

    his ambitions are realised he goes on to develop newambitions for himself, his company, builders and thecountry.

    He has achieved a lot in a fairly short space of time.His hard work, will to succeed and his determination

    has taken him to the top of his career as a servingboard member of one of the countrys biggest con-

    struction companies. Yet he remains humble andholds on to the traditional values he was taught byhis parents and grandmother while growing up as a

    dreamer in Soweto.

    Where it all beganChris always dreamed of a better life for his parentsand grandmother who he spent most of his formativeyears with. As a domestic worker she had very little,

    but was a proud and honest role-model who madehim believe in himself and his abilities. But, what set

    him apart from so many others children with dreamswas his ability to act on his dreams and make it hap-pen, if not today, someday.

    I would ride in the train from Soweto to Johannes-burg and as the houses changed from matchboxstyle houses in the township to big beautiful mansions

    in Johannesburg, I dreamed of one day owning abeautifully designed house with many rooms and

    big lush gardens.

    The contrast between the white and black peoples

    areas was so stark that as I got older my desire tochange this led to me becoming a political activist.While at school I became part of the movement and

    in 1976 my school, Morris Isaacson High School, wasat the forefront of the Soweto Uprising.

    Lucky breakDespite oppressive apartheid laws and thinking, Chrisfound immense kindness at the hands of a number

    of white people. They ultimately helped to shape hisearly years and ultimately led him to understand that

    people, life and business are removed from politics. It

    also taught him to judge people by their actions anddeeds rather than by race, class or classication.

    As a schoolboy he was singled out by an elderly whitelady that was a customer of the vegetable shop

    where he was a delivery boy. Alexandra Bungey,

    Started with a toiletChris traces his rst experience of building to the

    embarrassment he felt for his grandmother whenher township houses outhouse toilet started crack-ing up and people walking past the house could

    see inside the toilet.

    I could not stand for it and took the little bit of

    money I was earning at the greengrocer andbought the bricks and cementto rebuild it prop-erly. With no experience I rebuilt it brick-for-brick

    and done the best job I could.

    I am proud to say that the toilet is still standing

    today more than thirty years after I built it.

    SUCCESS

    took a liking to him and decided to

    help with his education by payingfor his school fees and buying his

    school uniforms.

    As a result Chris put everything into

    educating himself and when hematriculated he looked at followinghis dream of building nice houses.

    A chance opportunity arose whenhe spotted an advert for blackhigh school graduates interested

    in a career in architecture. Hewent for the interview and alongwith 11 other students was put

    onto a forward thinking programimplemented by the Institute of

    Architects. During his studies hewas assigned to MLH Architectsas a intern.

    Budding careerAfter graduating from Technikon Witwatersrand as anarchitectural technician his career blossomed withMLH Architects and many colleagues and mentors

    began shaping his career. Chris prospered at thecompany and despite initial misgivings of some of thedie-hard white business people that a black architect

    would not do as good a job, he kept his chin up andproved them wrong.

    The call to build rather than just design was still strongthough. Chris eventually took the leap (and his busi-ness skills) and opened his own building contracting

    business, CJB Builders. By then democracy had cometo South Africa and after landing some big housing

    contracts his rst dream to build nice houses was soonfullled. The success of the company led to biggerthings and next on his list was to work on contracts

    big enough to have overhead cranes on thesite. At the time that was to me the real deal,the real thing.

    He used his success and, by now, considerablebase of industry contacts to found and establish

    Rainbow Construction. As the CEO of Rainbowhis dream of undertaking big-scale buildingprojects became a reality and the norm. After

    a long and successful stay at the head of thecompany his last move has been his most am-

    bitious yet.

    My mission is to develop sustainable business based

    namely good old-fashioned honest dealings andhard work.

    I love my work and I enjoy dealing with a diverse

    range of people from different backgrounds. Buildingis still my passion and to me the real joy of building is

    when you return to a project after it has been com-pleted and occupied to bask in the glory of anothersuccessful project undertaken.

    Proudly South AfricanChris lifestyle has changed dramatically from thoseearly years and he shares his elegant house in Linden

    with his wife Phondliwe and children Nelisewe (19),Siphiwe (11) and Sanelisewe (2). He is a rm believer

    in family values and balances family life with his ac-tive social lifestyle.

    When he is not at home or working you will probablynd him on the golf course playing a deadly gameof golf with customers or business acquaintances. In

    fact, golf is another of his great passions and he andhis wife are members of the Johanneburg CountryClub. He has played golf with the countrys top busi-

    nesspeople, as well as South African golng legendErnie Els.

    When I played with Ernie I was quite nervous andwas conscious of my game, I didnt want to look likea rank amateur. But, he is such a good guy that he

    made me feel at ease and I actually learned a lotfrom that encounter.

    Just like in business I play a good honest game of golfand dont believe in playing differently just because Iam playing with a customer or potential customer. If

    you think you can beat me just because you hold avaluable contract in your pocket think again, laughs

    Chris in conclusion.

    FINDING FINANCE

    At the beginning of the year,

    Nurcha released its nancialoutputs from its inception to the

    end of last year. Lets look at theaccomplishments so far:

    Successfully lending hundreds of millions ofrand to emerging contractors who do notput any of their own funds into a project,

    and who provide no collateral, is Nurchasunique achievement.

    The contractors receive a great deal of sup-port and back up, while keeping control oftheir projects and their businesses.

    Nurcha, in association with Tusk and Sebra,manages the support to contractors ensuring

    the successful completion of projects.

    Nurcha offers bridging nance and a full range

    of support services nationally to contractorsand developers involved in the constructionof Subsidy and Affordable Housing, Infra-

    structure and Community Facilities.

    In nancing successful and protable devel-

    opment projects, Nurcha contributes to thegrowth of the smaller, mainly black-ownedconstruction companies. This is empowerment

    as it should be: adding value; creating jobs;helping mainly previously disadvantagedSouth Africans to reap the economic benets

    of the political transition.

    Financefor thePeople

    In the family of development financeinstitutions, Nurcha can boast impres-

    sive social and economic contributions

    to poor South Africans. These achieve-

    ments have been accomplished through

    the use of a small and limited capital

    base.

    In many instances, affordable houses are built with

    a single-pitch roof where the walls are raised higher

    on one side of the house to provide a natural pitch.In order to provide insulation against heat and cold,

    ceiling manufacturers recommend using the exposed

    beams to secure the ceilings.

    This saves the cost of brandering and bat-

    tens for the roof and, once the skill has beenmastered, it is easy to do. Another benet

    is that a window can be added in the highwall to allow natural sunlight in to both save

    the home-owner electricity for heating and provide

    light.

    Follow these instructions to get the job done right:

    Using Exposed BeamsIn this application, the beams perform a dual function,

    that of a load-bearingstructure as well as a

    decorative feature. TheNutec ceiling boards,plain or textured, are

    fixed on top of thebeams or betweenthem.

    General GuidelinesFor xing on top of thebeams, the followingsteps should be fol-

    lowed:

    The spacing of the

    beams must be at400mm centres or600mm centres for 4mm

    or 6mm Nutec ceilingboards respectively.

    The spanning capa-bilities of the board canbe increased by nailing

    brandering on the re-verse side of the board

    Ceilings forSingle-pitchRoofs

    CEILINGS

    24/402 Skills on Site April 2010

    at the appropriate centresbefore installation.

    The beams which are thefeature of this application

    must naturally be clean andstraight, as well as properlyaligned. Twisted or warped

    beams will negatively inu-ence the fnal ceiling.

    STEP 1Installing the board

    Fix boards on top of andparallel to the beams thus

    reducing the number ofvisible joints.

    For cross joints use H-prole jointing strips cutto size.

    STEP 2Adapting the roof

    structureFix counter battens

    on top of the ceilingboard directly abovethe beams.

    Take care not to damage the

    ceiling board when nailingon the battens.

    Fix waterproong mem-

    brane over counter bat-tens, allowing it to sagonto the ceiling board

    between the counterbattens.

    Fix battens or purlins forroong material over wa-terproong membrane

    through counter battens

    into the rafter.Pre-drilling of pilot holes isrecommended to reducethe possibility of damaging

    the ceiling board.

    Note:In cases where the roof structureand roof are already in position,

    it is necessary to install supportingtimber for the ceiling. Where thespacing of the beams is within

    the spanning capabilities of theceiling board, it is only necessaryto install a strip of supporting

    brandering on both sides of thebeams to which the ceiling can

    be nailed.

    CEILINGS

    A timber quadrant can beused to nish off the boardedges where they join the

    beams and the H-prolejointing strip cut to size can

    be used on cross joints.

    Where the beam spacing

    exceeds 600mm, a support-ing grid must be installed.

    Treating lateral dampLateral damp is treated by tanking that is, stripping

    the plaster off the bricks applying a cement sealantto the bare bricks to prevent damp penetration andplastering with damp-repellent cement in combina-

    tion with silicone injection, where necessary, to ensurethe prevention of rising damp (Fig B).

    WATERPROOFING

    Plastered PlinthThe plinth brickwork is the part of the wall betweenthe ground and the damp-proof course. This brickworkis usually good quality face brick. Bricks below the

    damp-proof course are always wet, but this presentsno structural problem. The problem occurs if the plinth

    is plastered. What happens is the moisture is trans-mitted through the walls to the exterior. The result isdamaged and eforesced plaster.

    5. The cubic metres of spoil is then multiplied withthe rate to remove the rubble to get to a cost.

    The rate is determined by the amount of spoil,type of spoil, dumping fees, type of machines

    and trucks used, distance to the dump, etc.

    6. The rate for the machines to demolish thestructure is added to the end price.

    ExampleHouse: 40m x 40m = 1600m2

    1600m2 x 1.6 = 2560m3

    2560m3 + 5% bulking factor = 2680m3

    2680m3 X R120 per cube = R322 560.00

    R322 560.00 + R5000 (machine)

    = R327 560.00

    Example:Site: 100m X 50m = 5 000m2

    5000m2 X 0.12 = 600m3

    600m3

    + 10% bulking factor = 660m3

    660m3 X R85-00 per cube = R56 100.00

    R56 100.00 + R5000 (machine) = R61 100.00

    To demolish a structure:1. Get the square metres of the structure.

    2. Multiply the square metres with 1.6 to get thecubic metres.

    3. Determine the percentage-bulking factor. Thepercentage is determined by the condition of

    the structure (thickness of walls, type of structureetc.)

    4. Multiply the cubic metres of spoil with thepercentage of the bulking factor to get thetotal for the spoil.

    The David Rattray Foundation has a rm beliefin providing sustainable solutions to disad-vantaged schools by ensuring maximum

    community investment and engagement. TheMablomong School Project uses traditional

    African-inspired architecture and design in order to

    capture the pride of culture and to promote com-munity engagement, with the

    intention of developing a costeffective and proud model forschool construction. The project

    provides school infrastructure

    that is perfect for teaching pupilswithin the connes of a traditional

    farm school in the Randfonteinarea on the West Rand

    Education and skills levels inRandfontein remain low, with

    the most recent statistics fromthe Randfontein Municipalityestimating unemployment at

    around 41%, while at least 24%of the population has not com-pleted primary schooling.

    Spirit of UbuntuCommenting on some of thebenets of the project, the AvengGroup human resources direc-

    tor Juba Mashaba said, Thisproject shows the true spirit ofUbuntu. We have witnessed a

    signicant level of communityinvolvement in this project, whichhas seen an administrative block

    built for the pupils, along witha sustainable skills transfer tothe local population. The proj-

    ect involved the training of 22formerly unemployed people

    in the rammed earth build-ing model. It also enabled 11teachers at Mablomong School

    to incorporate these methodsinto their curriculum, with thisproviding practical teaching to

    365 learners.

    Speaking on behalf of the David

    of mostly locally-mined soil toerect a building. This ensuresthat the use of cement, which

    involves high carbon emissions, is minimised. Given

    the poverty levels in this area, this cost-effective, low-maintenance method of building provides jobs andSETA-accredited skills development to the most needy.

    Furthermore, the design means that the buildings arere and pest resistant. They are also energy efcientbecause the heat captured from

    the sun during the day is radiatedback out at night as a source of

    warmth.

    Expanding nationwide

    The next step in the MablomongProject is to build a media centre thatwill include a library and computer

    centre, at the Mablomong School.Other divisions within the AvengGroup will also get involved in due

    course. Grinaker-LTA, for instance,will offer construction planning skills,

    while E&PC will provide water savingand waste management solutions.The Aveng Group and the David

    Rattray Foundation plan to expandthis project nationwide. Another

    similar project is also on the cardsfor KwaZulu-Natal.

    Crown Mines Primary School, LanglaagteTechnical School and the University of

    Johannesburg are the main beneciariesof Concors vision, which is to uplift the

    quality of life among communities whereit operates.

    We want to grow a partnership principle when se-

    lecting projects, explains communications manager,Sue Upton. Building relationships with people has a

    big effect on the results as we become personallyinvolved with people and forge bonds of trust andcooperation. We encourage communication through

    formal meetings and informal encounters as well asthrough regular phone calls.

    Concor, South Africas leading engineering, contract-

    ing and construction services group, is focussing onupliftment of education in two public schools which

    have long been starved of resources. The group is

    also assisting a local university.

    talks, Concor began upgrading the buildings, repairing

    the roof, renovating the ablution blocks and paintingthe classrooms. One of the most pressing needs was

    for an additional classroom, continues Sue. But wewent a step further, providing a large Portacamp

    which comprises one large and two smaller rooms,and the school was able to turn this into a library,a staff room and a kitchen. We also constructed a

    storeroom and laid paving on the school groundsand at the entrance

    Each year, Concor also sponsors the top learner inGrade 7, securing a place at the Langlaagte TechnicalSchool for this person to continue his or her second-

    ary education. Concor also provides fees, uniform

    and stationery. We also get involved in the schoolscelebrations, adds Sue. We fund the prize-giving,

    supplying trophies, medals and certicates.

    CooperationThe Langlaagte Technical School has seen the addi-tion of three new classrooms and the refurbishment

    of three more. We sub-divided the old mechanicalworkshop to create a fully equipped computer centreand two standard classrooms. One storeroom was

    converted into a classroom and an old masonryworkshop into a technical drawing room. All theclassrooms were tted with ceramic tile oors,

    suspended ceilings and light ttings.What is particularly rewarding about our work

    with these schools is the marvellous co-operationwe receive, Sue points out. The staff really goesthe extra mile to get the utmost out of their facili-

    ties, and work with us in trying to provide the bestpossible education for the children. For instance,

    the principal at Langlaagte purchased a softwareprogramme which is improving the childrens read-ing and writing skills by leaps and bounds.

    In addition, Concor awards a bursary to the toplearner to attend the University of Johannesburg

    (UJ) to read for a degree in civil engineering. Wesponsor the prize-giving ceremony at Langlaagtetoo. At both schools, we provide the ofcial sta-

    tionery as well as certicates.

    At UJ, Concor appropriately works with the engi-

    neering faculty, funding certain activities such aseducational tours.

    Each of the seven divisions within Concor alsonurtures its own specic social investment project.Wherever Concor is awarded a contract, the

    relevant division will identify a need within the com-munities where the work is situated and ensure thaton termination of the contract, the division leaves

    a lasting legacy. This could be a classroom, a clinicor a number of individuals with new, practical skills

    they can put to use immediately.
